How to catch "Error creating window handle."In my application, on some given actions while debugging in Visual Studio, I suddenly get a "System.ComponentModel.Win32Exception was unhandled"  Message="Error creating window handle." exception. The problem is that this exception isn't raised somewhere in a method, so it just shows up, and it causes the application to shut down. Is there anyway how to catch this kinds of exceptions? Can I put somewhere a general exception handler that will catch this kind of exceptions in my application? Thanks a lot in advance, any help our hints will be really appreciated! Pieter For those who would like some more info: I'm using Visual Studio 2.0 Beta 2, VB.NET, and it happens while closing a Dockcontent of the WeifenLuo DockPanel Suite).
